Document Summary
Chapter 6. 1. 6. 9 (cid:1)(cid:1) wavelength (lamda, ) distance a light wave travels to complete one cycle (cid:1)(cid:1) frequency (nu, ) number of wave cycles completed per unit time (usually in a second) cycles/second or sec. 1 or. Hertz (hz) (cid:1)(cid:1) wavelength = speed of light (3x108meters/second)/frequency =c/ (cid:1)(cid:1) frequency and wavelength have an inverse relationship (when one goes up the other goes down and vice versa) Energy of light max planck . where h=planck constant, 6. 63x10. 34 joule. second and =frequency in sec. 1. E in joules = hc/ where c=speed of light, 3. 00x108 meter/second and =wavelength in meters. Note: i will give you speed of light = 3. 00x108 meter/second and plank"s constant = 6. 63x10. 34 joule. second. You do not need to remember those numbers. I will not give you information on how to use them. 4. 7 light has both wave nature and particle nature. The individual particle is called photon named by einstein.
